Sex and mutations - testing the genic capture hypothesis. The proposed project will use a novel method to test a major outstanding theoretical problem in evolutionary biology and behavioural ecology. This will strengthen Australian research in this field and contribute to the growing international recognition it currently receives. The new methods developed will be useful to other researchers interested in mutation, sexual selection and the evolution and maintenance of sex.

This will strengthen Australian research in this field and contribute to the growing international recognition it currently receives. The new methods developed will be useful to other researchers interested in mutation, sexual selection and the evolution and maintenance of sex. Part of the project will be conducted in collaboration with a leading researcher in the UK. This will strengthen the links between institution in Australia and the UK.Read moreRead less
Quantifying condition-dependence in sexual selection. This research centres on testing evolutionary models of sexual selection. The project has relevance for understanding the role of mutations in reducing the fitness of populations and hence has implications for the conservation of endangered species and for human health. The research also investigates how investment in one trait, such as horns, will take resources away from another, like muscle. This has implications for animal production.

The project has relevance for understanding the role of mutations in reducing the fitness of populations and hence has implications for the conservation of endangered species and for human health. The research also investigates how investment in one trait, such as horns, will take resources away from another, like muscle. This has implications for animal production. The project utilises pest species as research models and will hence provide further understanding of pest life-history, knowledge critical to the success of control programmes. Australian science will further benefit through the research fellow's established collaborations with international scientists.Read moreRead less
Host plant choice by marine herbivores: ecological, genetic and historical constraints. Understanding the factors that determine plant choice by herbivores is crucial to predicting the ecological effects of herbivores on plants and herbivore adaptation to plants. This proposal aims to establish how evolution of host choice by a marine herbivore is constrained by ecological, genetic and historical factors. It will determine how the spatial arrangement of plants modifies host use, and whether evol ....Host plant choice by marine herbivores: ecological, genetic and historical constraints. Understanding the factors that determine plant choice by herbivores is crucial to predicting the ecological effects of herbivores on plants and herbivore adaptation to plants. This proposal aims to establish how evolution of host choice by a marine herbivore is constrained by ecological, genetic and historical factors. It will determine how the spatial arrangement of plants modifies host use, and whether evolutionary change by herbivores is constrained by genetic relationships among herbivore traits. The generality of important evolutionary hypotheses that predict plant choice by herbivores will be tested by extending such theory to new organisms and environments.Read moreRead less
Sources of genetic and phenotypic variation in sexual selection. This project will contribute towards Australia's reputation as a country where excellent and original research in evolutionary biology is conducted. The project will focus on the evolution of mate choice in the Western Australian rainbowfish, which has never been formally studied. Our research will therefore work towards a better understanding of Australian native fauna. Conceptually, the work encompasses new and innovative experim ....Sources of genetic and phenotypic variation in sexual selection. This project will contribute towards Australia's reputation as a country where excellent and original research in evolutionary biology is conducted. The project will focus on the evolution of mate choice in the Western Australian rainbowfish, which has never been formally studied. Our research will therefore work towards a better understanding of Australian native fauna. Conceptually, the work encompasses new and innovative experimental procedures that will address fundamental questions in sexual selection. The results will ultimately be geared towards publication in the highest ranking journals, thereby promoting Australian science on the international stage. Australian science will further benefit from the training of young scientists.Read moreRead less
Postcopulatory sexual selection and intraspecific variation in sperm competition traits. This project will contribute towards Australia's burgeoning reputation as a country where excellent and original research in behavioural ecology and evolution is conducted. By focusing on the evolution and function of sperm and genitalic traits, the project will address fundamental questions at the core of contemporary evolutionary research, thereby yielding results that will have a significant international ....Postcopulatory sexual selection and intraspecific variation in sperm competition traits.
